There's this really stupid show on History channel called Ancient Aliens. It's all about how they say extraterrestrials visited the earth before and what they left behind. They have a whole bunch of seasons with 1 hour long episodes about different topics. The people on the show have a whole bunch of theories about how aliens interacted with humans and sometimes destroyed them. I have watched a lot of them with my family. A few examples of episodes were about how humans evolved and the different species of humans (like Neanderthals). They are saying that aliens kept different species of humans in isolated areas to develop the perfect human (or homo sapiens) Another episode was about UFO sightings in Antartica and how there is a whole area which the US government has sectioned off to everyone. Its called the "No-Fly Zone" They mentioned a man who was part of a medical rescue team which had to fly over the area (because of a medical emergency.) and they saw a huge hole in the ground. And they landed and a bunch of soldiers showed up and told them to leave and not talk about it. I think this is a bunch of baloney and just some people ranting about extraterrestrials coming to visit. Another episode was about reincarnation and how some people report remembering with accurate detail their previous life. Now I'm not saying the reports were fake, (because they are true. And the people did recognize relatives from previous lives.) But somehow they manage to bring extraterrestrials and aliens into the mix by saying the aliens cause reincarnation. The show has facts like ancient grand structures which they say couldn't have been built without alien help, but they literally just take scientific facts and keep asking questions about it happened. Then when they find a way to supposedly say that humans couldn't achieve this feat then they say extraterrestrials came and helped. It's interesting, but really its just a bunch of conspiracy theories.
